And now Nchindo is said to be missing, and, according to some accounts, dead.

UPDATE: De Beers confirms his death and offers this statement:

We are deeply saddened by the passing of Louis Goodwill Nchindo, the former representative of the De Beers Group in Botswana. During his 30 year career, which started at Anglo American Corporation, followed by De Beers, and lastly Debswana, Louis Nchindo became a leading figure in the global diamond industry. Our thoughts and prayers are with his wife, children and grandchildren during these very difficult times.
